The canid domestication of homo sapiens brutalis

Humans and dogs have coexisted for a long time, it is extremely likely that we have altered each other's evolution (symbiotes and parasites always alter each other's genome). ... I thought I'd blogged on my wild speculation that it was the domestication of dogs that allowed humans to develop technology and agriculture (geeks and women can domesticate dogs and use a powerful and loyal ally to defend themselves against thuggish alphas) -- but I can't find that ...

...With this new ability, these protodogs were worth knowing. People who had dogs during a hunt would likely have had an advantage over those who didn't. Even today, tribes in Nicaragua depend on dogs to detect prey. Moose hunters in alpine regions bring home 56 percent more prey when they are accompanied by dogs. In the Congo, hunters believe they would starve without their dogs.

Dogs would also have served as a warning system, barking at hostile strangers from neighboring tribes. They could have defended their humans from predators.

And finally, though this is not a pleasant thought, when times were tough, dogs could have served as an emergency food supply. Thousands of years before refrigeration and with no crops to store, hunter-gatherers had no food reserves until the domestication of dogs. In tough times, dogs that were the least efficient hunters might have been sacrificed to save the group or the best hunting dogs. Once humans realized the usefulness of keeping dogs as an emergency food supply, it was not a huge jump to realize plants could be used in a similar way.

So, far from a benign human adopting a wolf puppy, it is more likely that a population of wolves adopted us. As the advantages of dog ownership became clear, we were as strongly affected by our relationship with them as they have been by their relationship with us....

The primary predators of humans, of course, are other humans. Women's need for protection against men is particularly acute. So which gender would be most interested in, and capable of, the domestication of a strong and loyal ally? What changes would a dog's presence make to a society and a species, and who would lose most when agriculture made dogs less useful?
